Walking through the woods one warm September day, Reinhardt and Kristine Ris pass a man who is in a state of agitation. Unusually in a small town, he does not return Kristine’s smile and drives off in a hurry. Near the end of their walk they make a terrible discovery: lying in a cluster of trees is the lifeless body of a young boy. It is a moment that will change their lives for ever.
Inspector Sejer is called to the scene, but can find no immediate cause of death. As the weeks go by, the appeal for the man seen in the woods to come forward remains unanswered. A once peaceful community is deeply shaken and the children lose the sense of complete freedom they had enjoyed. Then a second boy goes missing.
